论文摘要
本文涉及在交叉模块中具有系数的群体的非亚伯共同体学。这些物体是由Dedecker介绍的,并由Breen,Borovoi,Noohi和许多其他物体进行了研究。在本文中,我们研究了几个由这些共同体分类的重要对象,对它们而言,我们开发了一种类似于Schreier梗阻理论的理论。
This paper is concerned with the nonabelian cohomology of groups with coefficients in crossed modules. These objects were introduced by Dedecker and studied by Breen, Borovoi, Noohi and many others. In this paper we study several important objects that are classified by these cohomologies and for them we develop a theory similar to the Schreier obstruction theory of group extensions.
